VEHICLE-WHEEh- Specification of Letters Patent.

To all whom it may concern:

Be it known that I, FREDERICK J. LAN- CASTER, a citizen of the United States, and a resident of the borough of Manhattan, in the clty and State of New York, have invented a new and useful Im rovement in Vehicle- Wheels, of which the ollowing is a specification.

The object of my invention is to provide an improvement in vehicle-wheels; and it consists in providing awheel-felly and tire of rubber compound or analogous material and springs wholly embedded Within the tire.

. A further object is to provide certain improvements in the construction, form, and arrangement of the several wheel is produced in which the tire may be locked to the felly independently of the springs and the springs may be utilized for assisting in the resiliency of the tire.

In the accompanying drawings, Figure 1 represents in side elevation, partially in longitudinal central section, a portionof avehicle-Wheel, illustrating one embodiment of my invention. Fi 2 is a cross-section taken in the plane of theTine A A of Fig. 1. Fig. 3 is a view in side elevation of the form of spring which I choose to embed within the tire. Fig. 4 is an end view of'the spring. Fig. 5 -represents in side elevation, partly in longitudinal central section, a portion of a vehicle-wheel, illustrating another emb'odi.

ment of my invention; and Fi 6 is a crosssection taken in the plane of t e line B B of Fig. 5.

The vehicle-wheel spokes are denoted by The felly side plates are denoted by 3 and 4. The tire is denoted by 5 and is composed of rubber com ound or analo ous material. This tire is ocked to the fe ly against lon itudinal movement thereon. In the form s iown in Figs. 1 and 2 the interlocking means comprises outwardly-extending projections 6 on the telly and inwardly-extending projections 7 on the tire. In Figs. 5 and 6 the interlockin means comprises a pin-and-slot connection between the tire and felly side plates by rovidingthe side plates with radially-e ongated g rooves 8 and 9 and the tire with transparts whereby a verse pins 10, having their ends projecting into the said slots. i

The tire 5 is provided with a lurality of holes 11, extending transverse y thereto, into which holes are inserted springs 12. These springs have their axes substantially parallel with the axis of the wheel-telly and are held in position by the felly side plates 3 and 4. Each of these springs is radially compressible and comprises an annular series of flattened coils, so as to permit the springs to have a very extended eh agement with the Walls of the transverse hoTes in the tire. It will thus be seen that these springs are embedded wholly within the tire and serve to add to the resiliency thereof to a greater or lesser extent, according to the strength of the s rings. By forming each of these springs 0 an annular series of flattened coils it will be seen that there is no chafing action between the springs and the walls of the holeswithin the tire, and thus any tendency of the tire to wear at these points is obviated.

What I claim is 7 5 1. The combination with a wheel-folly and j a tire of yielding material, of radially-compressible springs embedded in-the tire, each spring comprislng an annular series of 0011s.

2. The combination with a wheel-felly and a tire of yielding material, of radially-compressible springs embedded in the tire, each spring comprising an annular series of longi tudinally-fiattened coils.

3. The combination with a wheel-folly and '85 a tire of yielding material, of radiaily-compressible springs embedded in the tire, each spring comprising anannular series of longitudinally flattened coils having rounded ends. v

4. The combination with a wheel-telly and a tire of yielding material having interlocls ing projections, of springs wholly embedded within the tire.

5. The combination with a wheel-telly and a tire of yielding material having interloclcing projections and side plates for confining the tire against lateral displacement, of springs wholly embedded within the tire.

6. The combination with a whecl-felly I00 having side plates, of xi tire of yielding mate rial located between the side plates, and mdially-c0mpressihle springs each comprising an annular series of coils extending across the tire transversely thereto, the said feliy side plates forming nbutnients for the ends of the springs and serving to hold the tire and its springs against lateral displacement.

In testimony that I claim the foregoing as my invention l have signed my name, in the :0 presence of two Witnesses, this 16th day of October, 1905. n

FREDERICK J. LANCASTER.
